feat(core): Coordinate workflow activation in multiple main scenario in internal API (#7566) 
Story: https://linear.app/n8n/issue/PAY-926

This PR coordinates workflow activation on instance startup and on
leadership change in multiple main scenario in the internal API. Part 3
on manual workflow activation and deactivation will be a separate PR.

### Part 1: Instance startup

In multi-main scenario, on starting an instance...
- [x] If the instance is the leader, it should add webhooks, triggers
and pollers.
- [x] If the instance is the follower, it should not add webhooks,
triggers or pollers.
- [x] Unit tests.

### Part 2: Leadership change 

In multi-main scenario, if the main instance leader dies…

- [x] The new main instance leader must activate all trigger- and
poller-based workflows, excluding webhook-based workflows.
- [x] The old main instance leader must deactivate all trigger- and
poller-based workflows, excluding webhook-based workflows.
- [x] Unit tests.

To test, start two instances and check behavior on startup and
leadership change:
